The Aztecs had strict rules of behavior. There was only one correct way to behave in every situation. Situations included what you wore, what you carried, how you walked, what you said, what you ate, how you greeted each other, how you treated your children and other people. There were even rules on facial expression and how you waved your hands.
All kids had to go to school. It was required because every citizen in the Aztec Empire had to know the way to behave correctly. It was the law. These laws of behavior were written down. If you did not behave correctly, you could be killed.
Here are a few of their rules of correct behavior:
Do not mock the old
Do not mock the sick
Do not mock one who has sinned
Do not complain
Do not make wry faces
Do not interrupt the speech of another
Do not carry a fan unless you are a noble
